COMBINED RANGE AND WATER-HEATER.

Specification of Letters Patent.

Patented Jan. 10, 19 11.

Application filed September 3, 1910. Serial No. 530,328.

To all whom it may concern:

Be it known that I, HILDEBERT VAN BUREN, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Combined Range and VVater- Heater, of which the following is a specification.

My invention consists of a water heating attachment for gas ranges.

It further consists of such an attachment in which water is heated from the burners for the ovens and from the top burners.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figure 1 represents a top plan view of a range provided with my improved waterheating attachment with the top frame re moved. Fig. 2 represents a vertical section of the range taken immediately behind the front of the range on the line m-m in Fig. 1. Fig. 3 represents a horizontal section of the range immediately above the oven-burners on the line g y in Fig. 2. Fig. 4 represents a transverse vertical section of the range on the line z-z in Fig. 3.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings :The range casing to which my attachment is applied is of a generally used type of gas ranges, having a base, 1, a backplate, 2, side-plates 3, a top-plate, 4, a top-frame, 5, having removable gratings, 6, and a horizontal oven partition, 7, which separates the upper baking oven, 8, and the lower broiling and roasting oven, 9, from each other. The upper oven has lining walls, 2 and 3*, respectively at the back and side walls of the casing, forming hot-air fines or chambers communicating with the lower oven around the edges of the partition. The front of the range has doors, 10 and 11, respectively closing said upper and lower ovens. The lining walls at the side-plates of the upper oven and the side walls of the lower oven have the usual horizontal guide-flanges, 12, for supporting grilles, pans and the like.

Burners 13, are supported between the top-plate and top-gratings, and said burners are illustrated as being like the water-heating burner for which Letters Patent, No. 911,347, were granted tome on February 2, 1909, and which burners will require no further illustration or description. Gas and air mixing tubes, 14, are connected to these burners and receive their gas supply from a pipe, 15, along the upper front and side edges of the range. The water chambers of the burners are connected by water pipes, 16, which are supplied from a vertical pipe, 17, at one side of the range and carry the heated water to a boiler or tank (not shown) or to wherever it may be desired, through a pipe, 18.

Beneath the partition separating the ovens are two or more burner tubes, 19, connected to the gas-pipe by a pipe, 15*, and each having two rows of perforations or orifices, 20, in its under side and divergently oblique, so that the flames from such flame-orifices may project downward and outward. A fiat heating coil, 21, is supported in a plane with the burner tubes, and has a central doubled loop, 22, the two parallel limbs of which are between the burner tubes and parallel with the same, and two doubled side loops, 28, the inner limbs of which are parallel with and alongside of the burner tubes. This coil has a feed-pipe, 24, connected to one end, and the other end of the coil is connected to the vertical water pipe 17, which conveys the water from the oven heater to the upper burner heaters. The doubled ends, 25, of the loops forming the coil are preferably downwardly curved and rest upon ribs or flanges, 26, upon the side plates of the range, and the ends of the burner tubes rest in two downwardly curved loops of the coil, as appears in Figs. 2 and 3, the tubes and loops being interjacent. Lighting ducts, 27, extend from the front of the stove to the organ burners to light the same from the outsi e.

The water passes from the boiler into thefeed pipe and thence through the flat heating-coil in the oven where it will be heated if the oven-burner is lighted, whence it will pass up to and through the top burners, be-

ing heated from whatever burners are lighted. As the flame orifices of the oven burner tubes diverge laterally, the flames from the same will lick around the adjacent waterheating pipes and heat the water in the same, without the water-heating device interfering either with the broiling or roast-- ing action of the flames and without the open structure of the heating coil interfering with the ascent of heat from the burners to impinge against the bottom of the baking oven and pass up through the surrounding air spaces. By this arrangement water will be heated Wherever a burner is active, and the heating of the water will be performed by heat otherwise not utilized and without detracting from the regular function of the burners. By employing the flat coil with water pipes parallel with the burner tubes and with the flame-orifices of such tubes directing the flames downward and laterally and obliquely diverging, the searing or broiling action of such flames will be maintained in the broiling and roasting oven without obstruction from the waterheating coil.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In an apparatus of the character stated, a burnertube having a plurality of laterally and downwardly diverging flame orifices, and a fiat water-heating coil substantially in the same plane as said tube and having the limbs of its loop at opposite sides of and parallel with the burner tube to have its flames lick around them.

2. In an apparatus of the character stated, a plurality of burner-tubes having each a plurality of laterally and downwardly diverging flame-orifices, and a flat water-heat- 1 mg COll substantially in the same plane as;

said tubes and having the limbs of its loops arranged at opposite sides of and parallel with the burner tubes.

3. In an apparatus of the character stated, a broiling and roasting oven, a plurality of burner tubes in the top of the same and each formed with a plurality of laterally and downwardly diverging flame orifices, and a flat water-heating coil substantially in the same plane as said tubes and composed of doubled loops having parallel limbs and such loops arranged interjacent with the burner tubes.

4. In an apparatus of the character stated, a broiling and roast-ing oven having ribs upon its side walls, a flat water-heating coil composed of doubled loops having parallel limbs and having the ends of said loops downwardly curved and supported upon the ribs of the oven, and burner tubes interjacent with the loops and formed with downwardly and laterally diverging flame orifices and having their inner ends resting in the downwardly curved ends of the loops of the heating coil.

5. In an apparatus of the character stated, a range casing having a horizontal partition dividing it into an upper and a lower oven, burners at the top of the casing and formed with communicating water-heating chambers and with an outlet pipe, a water-heating coil supported in the top of the lower oven and composed of doubled loops having parallel limbs and communicating with the upper water-heating chambers and having a supply, and parallel burner tubes interjacent with the loops of the coil and in substantially the same plane as the latter.
